In an effort to increase energy efficiency in multifamily housing projects, many utility companies offer free inspection services, and rebates and/or incentives to replace less efficient products with products that can lower energy bills and make residential living space more comfortable. HUD strongly encourages owners and management agents to contact their local utility company to determine what services are available. Some upgrades might be covered expenses under HUD’s new Green Retrofit Program (HUD Notice 09-02), and some may be eligible Reserve for Replacement items.
